+   syswrap-amd64-linux.c and syswrap-ppc32-linux.c, and associated
+   vki*.h header files, constitute Valgrind's model of how a vanilla
+   Linux kernel behaves with respect to syscalls.
+
+   On a few occasions, it is useful to run with a kernel that has some
+   (minor) extensions to the vanilla model, either due to running on a
+   hacked kernel, or using a vanilla kernel which has incorporated a
+   custom kernel module.  Rather than clutter the standard model, all
+   such variant handlers are placed in here.
+
+   Unlike the C files for the standard model, this file should also
+   contain all constants/types needed for said wrappers.  The vki*.h
+   headers should not be polluted with non-vanilla info. */
